Enthuware 1ZO-894 question - confused

[Paul Statham]

Edit: Ignore, it was me being stupid


So the question says

Given:

<%
Map m = new HashMap();
m.put("m", "n");
m.put("n", "o");
m.put("o", "p");
pageContext.setAttribute("map", m, PageContext.PAGE_SCOPE);
%>

Which of the following will output p? (choose 2)

A. ${map.(map.n)}
B. ${map[map[n]]}
C. ${map.o}
D. ${map(map(n))}
E. ${map.map.n}
F. ${map["o"]}

Answers are C+F, I'm confused by C.

The . operator is reserved for attributes and java beans, yes map is an attribute but it references a map object?

Hi

I can analyze the C and F answers for you as following:

C. ${map.o} Correct

After the . "Dot" operator, it can be followed by map key or bean property.
And in [] , It can be followed by [same as dot] and index of collection or Array
